Describe the bug
It won't go past PZEM004Tv30 pzem1(Serial1, 1); The Teensy 4.1 just hangs. Audible sound can be heard, it's like plugging/unplugging a USB device on your PC.

To Reproduce

  1. Let's use the Blink sample sketch.
  2. include PZEM v3.0
    #include <PZEM004Tv30.h>
    PZEM004Tv30 pzem1(Serial1, 1);
  3. Upload the sketch.

Expected behavior
The built-in LED will not blink as expected. Instead, audible sound can be heard and it is like plugging/unplugging a USB device.
